Overview
You are observing that statistics stopped displaying recently on your MGR or STV server at http://<MGR/STV server IP>/tpm
and hence, the graphs are showing blank for a recent time period.
Solution
This issue occurs when there's a backlog of services that the systems are not able to keep updated in the database. The old files are updated first. If this backlog keeps on increasing and you observe that the newer data is not coming up, then the old backlog needs to be deleted using the below steps.
Note: These steps cannot be undone.
- SSH into the MGR/STV server.
- Change the directory using the
cd /var/TextPass/STV/collector/data/
command. - Run
ls -lth *.yml
to list the YML files that need to be deleted. The files with their timestamp information will be listed with the oldest files towards the end of the output of the command. - Run
rm -rf <filename>.yml
to delete the old files as per your requirement.
